During the latter half of 2006, after an injury to Zach Thornton, Pickens started in goal for the Fire even once Thornton was match fit again. This also included his first play-off start on October 22, 2006 for the Fire, keeping a clean sheet in a game that the Fire won, 1-0 thanks to a goal from Justin Mapp in the 35th minute. Zach Thornton was traded to the Colorado Rapids before the 2007 season, clearing the way for Pickens to start.

In February 2008, Pickens signed a deal with Queens Park Rangers until the end of the 2008 season.[1] In May 2008, it was announced that Pickens would not have his contact extended and that he would be released by the club at the end of June.

As of December 2010, Pickens has been called up to five United States training camps, including the camp in January 2011. However, he has never earned a national cap or been part of the final 18-man roster.[7]
